rotors: OEM vs Mercedes genuine
Hey all,
So is the consensus that the stock rotors are the best for us on the market?
On pelican parts they list OEM rotors as well as Mercedes genuine. The OEM are about $30 less each, but is there actually a difference? Is the genuine part the same part you would get from the dealer?

brakes
Mintex all the way, discs and pads .They have been making them for years.I have fitted them on all my cars for 50 years never had a bad set. Just fitted them on my 260e fraction of the cost of original ones. Good luck by the way.

The M-B rotors have an aluminum hub with the steel disc mounted to the hub with steel pins. The reason for this is to reduce heat transfer to the wheel bearings.
The internal fins are directional to maximize the pumping efficiency and thus, the cooling effect, which is why there is a left and right rotor. If the picture on the Pelican site is correct, the OEM is the same as the M-B rotor.
There are other options and some will say there is no reason to use the expensive M-B or OEM rotors.

So the OEM are the ones I want from pelican then. Thanks.

Our light weight rotors can reduce 4.3lbs per rotor, and once they are replaced you will probably not need to replace them again, so if you intend to keep the car in a long term, RB two piece rotors can actually save you more money than the lower cost one piece rotors.

Lol sounds like advertising^^^
I know you do a lot of track and auto cross. Save money and buy a w203 sport calipers and rotors. They will outperform the stock c43 setup all day at the track

Is there any data or articles you can refer me to that support this? Very few people here track their cars and often do this type of conversion strictly for cosmetic reasons.

Racing brakes are great to go(No Doubt),
stock C43/E55 Rotors are little costly, comparing to other brothers,
some guys including me, looking for less $$$ with more power & efficiency brakes, many option can be hold,
i used & using a good alternative OEM Rotors less priced than stock Rotors(which i don't think worth to spend),
if we go with theory of L/R cooling, why AMG not constantly made those for their other more powerFUL, like all 55K's>>6.2l>>>5.4 bi-turbo,,
i used Rotors from W220 4-matic, for about 2.5 years without any issue & still survival..

cheaper to have one tooling for both brakes instead of 2. are those other cars 2 piece rotors? if not i would again assume it was to make the parts cheaper.
going to look into the w203 sport rotors, anyone have the specific part#s? i think there is a thread, but i thought they required modification to the hubs or something, which isnt what i want to do.
i dont mind the cost of the OEM rotors, i want a good rotor is all, prefferably not a smaller one or a 1-piece.

If you futurity think to replace the ring instead of complete Rotor, you can get RB racing Rotors,
*as i know, MB got agreement contract with Brembo & SGL to producing lightweight Rotors with usable Rotor Hat, with more costly,
cause they don't want any kind of investment copying from any commercial trading companies,,
Brembo & MB knows it will be horrible pricey to any companies for copying 2 piece Rotors..!!

I do 3-4 tracks days a summer so the drilled rotors will be helpful to keep the pad temps down.
also, are you saying that there is a way to just buy rotor rings for the OEM mercedes rotor hubs? or are you just saying i could do that with the RB rotors?
I dont like the C230 sport pad idea, saves a ton of money but i jost dont like the 1 piece construciton and they are 4mm smaller i would worry about the pad edge. RB rotors are only 2mm smaller so thats only 1mm on each side so its damn close to the stock size.

If we talking about drilled Rotors, alternative OEM Rotors will do the job, but if you need less weight with re-using Hats, RB brakes will be great solution,
Rotor dia. is not that important, should be more considering about thickness,
i don't like to use C230 Rotors either, cause its 28mm vs 32mm, many other models drilled or non-drilled got the same C43/E55 Rotor thickness, with 4mm less (which i don't think it's that big deal),
if you want to go with 334x32, you can get R129 Rotors, should to use 2mm washers to clear the ball joints..!

"If we go with theory of L/R cooling, why AMG not constantly made those for their other more powerFUL, like all 55K's>>6.2l>>>5.4 bi-turbo,,"
Actually, AMG does consistently provide rotors that have more efficient cooling vanes and thus need to be left/right specific, as do most manufacturers of high performance cars, such as Porsche and Ferrari. The rotor is basically a pump impeller (the fluid in this case is air) and you never see straight vanes on pumps where efficiency matters. You can easily see the shape of the vanes on drilled rotors; the holes, which are between the vanes, are swept back, they do not follow a line radially from the hub.
The holes drilled through the rotor are to dissipate gas buildup between the pad and rotor, not to add cooling.
See the attached photos of M-B C43 rotors. I have also attached a photo of the rotors on my Porsche, where you can clearly see the "swept back" shape of the internal vanes by the pattern of the holes.

Good info.,
the only models which i know using L/R cooling room are "92-95 W124 500E/E500 & R129 500SL/SL500", and "W202 C43 & W208 CLK55 & W210 E55",
can you tell me which other models AMG providing L/R cooling after those..??
as i see; all AMG models uses regular vent room, including new ceramic Rotors, isn't..??
hope i'm NOT wrong..!-!

I haven't checked every single model, but if you go into the EPC you will see that 210, 211, 212, 217 AMG list Left/Right rotors. Some, such as the 222 with "bond" rotors (which I assume means carbon ceramic) clearly show the swept vane pattern but are not listed as Left/Right. Odd, because swept vanes are less efficient when turning "backwards".

I don't think W211 got L/R cooling..!,
for my research; i found all AMG performance package P30/P31/P33/-P98, doesn't have L/R cooling,,
they got bigger drilled room/lightweight/less corrosion, better material...!!

The parts system says the 211 did.
I think I figured out the "bond" rotors. the disc is bolted to the hub. The rotor can be removed from the hub and reversed. So they are Left/Right without having a separate part number.

Ooops. My mistake. The 211 list one part number for front rotors. However, there is a note saying that E55 rotors can only be replaced in pairs. I don't know what that is about.
